A RMCO— Rust-Resisting Iron 
Its Discovery Confirms What the Ancients Guessed 
T HE rust-resisting qualities of pure 
iron were ignored for ages. The 
ancients made pure iron, though 
they may not have known the great value 
of it. Thousands of years ago men made 
tools out of iron. Possibly they used steel, 
too. But, if they did, the articles have long 
since gone up in rust. Rust is the great 
enemy of steel. For many uses where great 
strength or hardness is required, steel is 
necessary—but it rusts rapidly. The very 
things that are mixed into iron to make it 
steel cause it to crumble away in rust. 
The more nearly iron is free from all 
impurities the greater its rust-resisting 
power. The iron that has lasted since the 
Pyramids were built is mighty free from 
impurities. The pure iron in the sacred 
pillar at Delhi, India, has stood through 
twenty-eight centuries of weather. 
America furnishes her own instances of 
the long life of iron. In 1910 an old iron 
link suspension bridge was torn down at 
Newburyport, Mass. After a hundred 
years of exposure the rust on those links 
was scarcely as thick as a coat of varnish. 
But you’ve seen proof on your own farm 
of the superiority of iron over steel. 
Look at these two nails 
The iron nail has seen thirty-eight years 
of service while the round steel nail is gone 
with only eleven years’ use. You have A 
seen many such comparisons. Did you 
ever wonder why there is such a differ¬ 
ence in their rust-resisting qualities ? 
We did. And we set to work to find 
out why most metals rusted, though some 
did not. 
The iron that has lasted we found to be 
almost pure. But pure iron is hard to 
make. You add more impurities to already 
impure iron to make steel. Impurities 
must be taken out to make pure iron. It 
never had been done on a profitable com¬ 
mercial basis. The links at Newburyport 
were from iron purified by crude methods 
and wrought by hand. 
Ideal iron commercialized 
Iron made by hand couldn’t compete 
with steel. We knew that. But we were 
determined to make pure iron. We have 
done so. And we are continually making 
more and more. We have commercialized 
an ideal. 
Pure iron is Armco— 
American Ingot Iron 
That is the name of our product. When 
we first began to make pure iron we called 
it American Ingot Iron. That name is 
still widely used. Remember, Armco and 
American Ingot Iron are the same, mean 
the same, pure iron. Armco is the purest 
iron commercially manufactured in the 
world. Armco Iron is purer in content 
and more uniform in texture than the iron 
pillar at Delhi, the links at Newburyport, 
or the iron nails that served your fathers 
so well. 
Armco Iron is guaranteed 
to be 99 84/100% pure iron 
Not a batch of molten iron leaves our 
furnaces until chemical tests in our labora¬ 
tory show 99 84/10096 — ®r higher — 
purity. American Ingot Iron may be 
higher than 99 84/100% pure. It is never 
lower. We guarantee that. 
Pure iron roofs last 
seventy years 
You’ve heard of the good tin roofs that 
were laid a hundred years ago. Did you 
know that the core, the sheets that were 
tinned, was of pure iron? And today you 
can get the same grade roof—or higher— 
made of American Ingot Iron. 
You can now have pure iron shingles, 
iron sheet roofings and sidings, metal lath, 
iron gutters, flashings and drain pipes that 
will last as long as your buildings. 
There’s a second reason—in addition to 
its pure iron base—why American Ingot 
Iron roofing is better than ordinary sheet 
metal. The galvanizing on Armco roofs is 
better. 
Steel dissolves in galvaniz¬ 
ing much faster than 
Armco Iron 
When a sheet of steel is dipped in the 
galvanizer it begins instantly to dissolve. 
American Ingot Iron, because of its purity, 
shows practically no dissolution when the 
zinc galvanizing is applied. Therefore the 
zinc coating is purer and will last many 
times as long as the galvanizing on ordinary, 
impure material. 
Armco Old Style Terne plate, with its 
Armco Iron base, is made by the More- 
wood hand dipped, old style, pure palm oil 
process. Absolutely no acids are used in 
the process. The coating is pure lead and 
tin—two almost indestructible metals. 
There are seven operations. No higher 
grade metal roofing is made in the whole 
world. Each shingle is stamped Armco 
Thousands of farmers 
demand iron roofing 
Write for booklet on Armco Iron Roofing 
A canvass of farmers showed us the way 
iron roofing is taking high place among 
roofings. Out of 8000 farmers using metal 
roofings 5000 had bought iron. Your 
metal roof should be Armco — the only 
99 84/100% pure iron roof. Every sheet, 
flat or corrugated, bears the Armco trade 
mark. Take no other. Write today for 
Armco Roofing Booklet. 
Who pays your road tax? 
That’s just a suggestive question—a 
suggestion that you have some right to say 
what that road tax is spent for. If it’s 
culverts your roads need, here are a few 
reasons why you should urge your super¬ 
visor to install Armco—American Ingot 
Iron Corrugated Culverts. Their dura¬ 
bility is insured by the purity of Armco Iron 
—its rust-resisting power—and the quality 
of the galvanizing. 
The deep corrugations give strength to 
carry the heaviest loads and deepest fills. 
Armco Culverts have an enormous resist¬ 
ance to external strains. Armco American 
Ingot Iron Culverts are quickest to install. 
And because no machinery nor cementing 
is necessary, they are cheapest to install. 
If you need a culvert on your farm we 
will gladly tell you where you can secure an 
Armco American Ingot Iron of desired 
size. 
Water tanks need not rust 
Write for names of tank manufacturers 
using American Ingot Iron 
You can secure storage tanks, pressure 
tanks or stock watering tanks of Armco 
Iron. A tank like the one shown here will 
last as long as its heavy supports of steel. 
These supports are made of steel so that 
they will carry the heavy weight. The 
tank itself should be Armco Iron. 
Silos are built of Armco Iron 
Write for names of silo manufacturers who 
use Armco Iron 
The buildings on a dairy farm can well 
be made of Armco Iron. The roof on the 
cow stable, the ventilators, the window 
frames, and finally the silo can be built of 
rust-resisting, almost everlasting Armco 
Iron. 
Handsome and durable fencing—Armco 
Iron Woven Wire Fencing—is made by 
the Page Woven Wire Fence Company. 
Things under shelter 
rust quickly, too 
Write for names of stoves and ranges 
made from Armco Iron 
There’s the gasoline sto.ve, the water 
heater, the kitchen range. They rapidly 
rust out unless made of pure iron. Alter¬ 
nate heating and cooling hurry the process. 
The gases of combustion quickly eat into 
low grade iron and ordinary sheet steel. 
But Armco Iron resists such attacks. 
Enthusiastic stove manufacturers, using 
Armco Iron, guarantee against rust for 
twenty-five years. 
Ice box and furnace can 
be of Armco Iron 
Write for list of furnace and refrigerator 
manufacturers using American Ingot Iron 
Yourice box, especially if it is enameled, 
should have a base of Armco Iron. Cer¬ 
tain manufacturers use it for all enameling 
purposes. Armco takes a smoother coat, 
is free from pin holes and bubbles, and—is 
slow to rust. 
And if there’s anything that should stand 
against rust it’s a furnace. You can have a 
furnace with its vital parts made of Armco 
Iron. We’ll tell you the furnace manufac¬ 
turers who use Armco Iron if your dealer 
doesn’t show you the Armco trade mark 
on the furnace he tried to sell you. 
You’ll find this Armco triangle in blue 
on all American Ingot Iron sheet roofing, 
culverts, silos and water tanks. It is your 
guarantee of. iron — rust-resisting iron— 
99 84/100% pure. 
When you see it you are safe in buying 
the article as being of pure iron. If it isn’t 
marked Armco, ask for proof that the iron 
used is Armco—the pure iron.
